* perf annotate: Add basic support to event group viewNamhyung Kim2013-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add --group option to enable event grouping. When enabled, all the group members information will be shown with the leader so skip non-leader events. It only supports --stdio output currently. Later patches will extend additional features. $ perf annotate --group --stdio ...

* perf tools: Allow user to indicate path to objdump in command lineMaciek Borzecki2012-09-05
| | | | | | | | | | | | When analyzing perf data from hosts of other architecture than one of the local host it's useful to call objdump that is part of a toolchain for that architecture. Instead of calling regular objdump, call one that user specified in command line.

* perf report: Accept fifos as input fileRobert Richter2011-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default input file for perf report is not handled the same way as perf record does it for its output file. This leads to unexpected behavior of perf report, etc. E.g.: # perf record -a -e cpu-cycles sleep 2 | perf report | cat failed to open perf.data: No such file or directory (try 'perf record' first) While perf record writes to a fifo, perf report expects perf.data to be read. This patch changes this to accept fifos as input file. Applies to the following commands: perf annotate perf buildid-list perf evlist perf kmem perf lock perf report perf sched perf script perf timechart Also fixes char const* -> const char* type declaration for filename strings. v2: * Prevent potential null pointer access to input_name in builtin-report.c.

* perf tools: make -C consistent across commands (for cpu list arg)David Ahern2011-11-28
| | | | | | | | | | | | | | | | | | | | | Currently the meaning of -C varies by perf command: for perf-top, perf-stat, perf-record it means cpu list. For perf-report it means comm list. Then perf-annotate, perf-report and perf-script use -c for cpu list. Fix annotate, report and script to use -C for cpu list to be consistent with top, stat and record. This means report needs to use -c for comm list which does introduce a backward compatibility change. v1 -> v2 - update perf-script.txt too Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1321209008-7004-1-git-send-email-dsahern@gmail.com Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

* perf annotate: Make output more readableStephane Eranian2011-08-18
| | | | | | | | | | | | | | | | | | | | This patch adds two new options to perf annotate: - --no-asm-raw : Do not display raw instruction encodings - --no-source : Do not interleave source code with assembly code We believe those options make the output of annotate more readable. Systematically displaying source can make it hard to follow code and especially optimized code. Raw encodings are not useful in most cases.

* perf report/annotate/script: Add option to specify a CPU rangeAnton Blanchard2011-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an option to perf report/annotate/script to specify which CPUs to operate on. This enables us to take a single system wide profile and analyse each CPU (or group of CPUs) in isolation. This was useful when profiling a multiprocess workload where the bottleneck was on one CPU but this was hidden in the overall profile. Per process and per thread breakdowns didn't help because multiple processes were running on each CPU and no single process consumed an entire CPU. The patch converts the list of CPUs returned by cpu_map__new into a bitmap for fast lookup. I wanted to use -C to be consistent with perf top/record/stat, but unfortunately perf report already uses -C <comms>. v2: Incorporate suggestions from David Ahern: - Added -c to perf script - Check that SAMPLE_CPU is set when -c is used - Update documentation v3: Create perf_session__cpu_bitmap() Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: David Ahern <dsahern@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Link: http://lkml.kernel.org/r/20110704215750.11647eb9@kryten Signed-off-by: Ingo Molnar <mingo@elte.hu>
